Embodiment

1, in Fig. 1 embodiment, the presetting method of the predetermined depth (20) of wheel body walking is: temporarily open hand reducing pressure valve (31), when caster is in full reduced time position (21), lever (4) is in energising movable contact (3) and just departs from the mark of electrical contact plate (1), the length h of turn-knob telescopic adjusting bolt cover (6) adjustment kickboard push rod (5) ₁, make kickboard waterline to the height h of wheel body cylindrical minimum point ₂it is just in time the Suitable depth of wheel body walking.As the normal condition of wheel body walking.The mechanism that caster stretches out thus is: wheel body is met mud pin and exceeded the default degree of depth when sinking, frame (11) declines thereupon, but the buoyancy of kickboard (7) makes the relatively upper top of kickboard push rod (5), lever (4) outer end up interlock energising movable contact (3) is up, circuit is connected immediately, electromagnet (29) related sliding plug is immediately up, back oil road (26) is closed while opening high-pressure oil pipe (24) oil circuit, high pressure liquid oil trailing wheel axle center (13) place passes through, transfer the pressure to hydraulic jack B, piston rod (18) is stretched out and promotes caster extension and contraction control rotating disk (15) to rotating clockwise, caster is stretched out by caster slider bar (22), stretch out in process once be inserted into the enough hard mud pin strong point, both can prevent the gravitation of wheel body to sink, the adhesive force that the enough hard mud pin strong point can be relied on again significantly to increase driving prevents skidding from sinking.Caster retraction mechanism is: when powerful hydraulic coupling caster pushed away stretch make wheel body increase just beyond predetermined depth time, because kickboard (7) does not rise with frame, its gravity is drop-down, make energising movable contact (3) descending disengaging electrical contact plate (1), circuit disconnects, returning pull-spring (30) drop-down, back oil road (26) is opened from oil return opening (8) oil return while making sliding plug blocking-up high-pressure oil pipe (24) next oily, hydraulic pressure rapid drawdown after hydraulic selector (25), caster outer end is by the powerful compressing of power F, namely with caster slider bar (22) for balance pivot, pushing caster extension and contraction control rotating disk (15) is to counterclockwise rotation, caster bounces back.Power F results from reaction force and the locomotive weight that wheel body inhour rotates caster compressing earth in advance.The locking of so-called caster, except be in when caster stretches out entirely and full reduced time of caster time state except, be stretch with in the relative extension elongation maintained in short-term of caster in contracting alternately.The height of mud pin is unordered, make energising movable contact (3) be often in unordered energising and power-off constantly alternately in, the corresponding flexible of its caster that at every turn links has some time delays, thus causes some walkings to rise and fall.But due to kickboard stablizing in level height, because the interlock reaction of this device is quick, make wheel body be walk at the small size up and down waveform of predetermined depth (20) substantially, substantially maintain and all deeply advance.This specification be with rice field Work machine design need following data instance be described: the locomotive speed of travel be 2-3 km/time; Plow layer Suitable depth (namely wheel body walking is normally absorbed in the degree of depth) is 17 cm, and 37 centimetres (presetting the maximum extension elongation of the walking degree of depth+caster) below controllable to mud face, paddy field, has adapted to most ultra-deep fields condition.Reach that the utility model is automatically controlled, space-time fiting effect between hydraulic pressure, machinery, key makes the caster speed of stretching out surmount wheel body subsidence velocity to arrive mud pin in advance.Mud pin due to ultra-deep all still has bearing capacity in various degree, and the larger this bearing capacity of wheel body contact area is larger, and the caster simultaneously entering plow layer and mud pin may have two or three, greatly can delay wheel body; Due to the high pressure liquid oil accuracy of transmission of pressure and instantaneity extremely strong, as long as hydraulic pressure keeps enough, the reaction of stretching out of caster can be appropriate soon, makes it to realize above-mentioned effective space-time cooperation.Sagging actual presentation can be greatly reduced visible when the wheel body of normal condition walking dashes forward the dark bank of meeting ultra-deep 20 cm, caster stretches out within the time being inserted into the end only needs wheel body to sink to the half of the time end, by wheel body support in a high position, after this only slightly can need continue to stretch out and preset height can be returned in wheel body top for this reason.Also known thus, the weight that the power that the caster that stretches out during mud pin ultra-deep supports wheel body carry much smaller than wheel body, the hydraulic pressure energy consumption needed for support increases actual also little, but it anti-ly falls into energy consumption that control can avoid deeply and waste much bigger.According to rough statistics, nearly 3 times when the energy consumption of the hand tractor wheel body walking degree of depth 40 centimetres time is 17 centimetres.The know-why also related to is: due to wheel body advance between the important rule of sinking be skid---cutout mud pin------deep-cut downwards until wheel body torsion all transfers to from horizontal direction to be absorbed in increase by resistance increases---skidding cutout sink increases the weight of quickening---, caster is inserted into the enough strong points of hardness early and can holds on to mud pin for this reason, ensure the enough of horizontally tracting effect, pole prevents sinking of skidding and cause effectively; Due to the caster that stretches out ultra-deep field stay be insert under the jack that pulls up, very little to the damage of mud pin, the extensive damage that wheel body can be avoided to get deeply stuck in, makes mud pin become better year by year.

2, Fig. 2 and Fig. 3 is that the utility model is arranged on the expansion embodiment of ploughing on the machine of inserting.Plough the machine of inserting can once cross machine complete simultaneously plough rake, slurry is played on mixed fertile, pressure grass, top layer, it is flat to drag, rice transplanting etc. is from ploughing to slotting whole operations, working width 120 centimetres, net weight 450 kilograms, after carrying seedling, gross weight is about 520-550 kilogram, come into leaves and take turns each load-bearing about 220 kilograms in left and right two, overall mass is than large 100-200 kilogram during big-and-middle-sized hand tractor band rotary cultivator attachment.Lobe outside its rotary tillage tractor, come into leaves wheel, impeller, the two-way anti-of extension lobe extension elongation fall into the new technology devices such as blade, make it have than other machines better anti-sunken performance, can realize not touching bottom row in more ultra-deep field and walk operation, installing this device is fall into change its " anti-fall into do not control dark " for not only strengthening is anti-further but also automatically controls the degree of depth of walking.Technical scheme is: overlapped by the utility model 3 and be arranged on two respectively and come into leaves wheel outside and rear steering wheel, substitutes impeller outer pleurapophysis tooth (34) with the stretch caster of linked system D of caster and extends the two-way anti-sunken blade of lobe.

In figure 3, the upper fixed installation of slotting captain's impeller outer side end cap (32) is being ploughed as lower component: the rotating disk groove of caster extension and contraction control rotating disk (15) is at meta; Caster slider bar (22) is circumferentially; The rotating shaft stake that circular hole on hydraulic jack B termination is inserted in is on proximal cover circumferential edge position.Owing to ploughing the original anti-sunken better performances of the machine of inserting, therefore caster can reduce by half, and interval retains the impeller outer pleurapophysis tooth (34) on impeller linear leaf (33).In fig. 2, ploughing the machine of inserting is to rank forefront carrying and drive complete machine main body with two, the left and right work wheel that comes into leaves, and caster is arranged on outside impeller and both sides impeller can be made all substantially to control dark by same predetermined depth and all deeply walk.In like manner, driving type direction trailing wheel also can realize control substantially with front-wheel and deeply all deeply walk, and makes to plough platform headed by the machine of inserting one-tenth and substantially automatically can control the Novel rice paddy machinery of dark walking operation by unified predetermined depth.Direct effect the 3-4 of completing mu per hour can be kept from the unprecedented high efficiency of ploughing to inserting in the field existed in a large number, ultra-deep is more serious.Only need once cross machine make mud pin seldom impaired owing to leaving jack less and per season rice; Make this machine can be designed to the higher type of the larger efficiency of working width because the dark performance of anti-sunken control significantly improves; Owing to ploughing, to plug in machine two wheel that comes into leaves wide to full working width final decision tilth, therefore control its walking degree of depth and namely control tilling depth; Rotary tillage tractor due to this machine is arranged on front leading cutout and is beneficial to higher than the mud pin of predetermined depth and all deeply walks, all be beneficial to the significantly raising of overall efficiency benefit, support the expanding species of paddy rice especially double cropping rice, support the larger adjustment of industry labour structure, support that rice district builds economizing type environmental protection type agricultural.
